主要使用 pillow

如果没有安装 使用 pillow install pillow 安装一下

看代码：

from PIL import Image

import argparse

#字符画所用的字符集

ascii_char = list("$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,\"^`'. ")

def getChar(r,g,b,alpha=256):

if alpha == 0:

return ' '

length = len(ascii_char)

gray = int(0.2126 * r + 0.7152 * g + 0.0722 * b)

unit = (256.0 + 1)/length

return ascii_char[int(gray/unit)]

parser = argparse.ArgumentParser()

parser.add_argument('file')

parser.add_argument('-o','--output')

parser.add_argument('--width', type = int, default = 80)

parser.add_argument('--height', type = int, default = 80)

args = parser.parse_args()

IMG = args.file

WIDTH = args.width

HEIGHT = args.height

OUTPUT = args.output

if __name__ == '__main__':

im = Image.open(IMG)

im = im.resize((WIDTH,HEIGHT),Image.NEAREST)

txt=""

for i in range(HEIGHT):

for j in range(WIDTH):

txt += getChar(*im.getpixel((j,i)))

txt += '\n'

print(txt)

if OUTPUT:

with open(OUTPUT,'w') as f:

f.write(txt)

else:

with open('output.txt','w') as f:

f.write(txt)

再看带参数执行：
